The Characteristic of Water Injection Response to Complex Reservoir

Water injection is a main method in the development of oil field in order to obtain high recovery efficiency, especially for the complex reservoir. This paper is concerned with water injection development of complicated stratum reservoir. It introduced the special condition of the water injection area, and 5 factors influencing water injection result. By means of statistics, the paper concluded the common characteristic of validity of production wells response to injection wells and the difference of the validity for 6 aspects. The gap of the validity between different oil wells is big. By using comparative method, the paper summarizes that the reservoir formation connectivity is the key control factor to the validity, the basic stratum correlation is important. The conclusion can be used for the analysis of other oil field.
